Waegwan (Korean: 왜관) is the seat of government for Chilgok County, North Gyeongsang province, South Korea.

In the summer of 1939, Korean and Japanese students from the Daegu Normal School (now the teachers' college of Kyungpook National University) were sent to Waegwan to do forced labor on the Gyeongbu Line railroad tracks.

Monuments to the UN and South Korean forces now stand on the low mountain overlooking the northeastern section of the city, which is locally known as "Jagosan" and known in military reports as Hill 303.

In an attempt to slow the Northern advance, on August 3 American forces blew up the bridge at Waegwan while hundreds of refugees were crossing.

On August 27, 1950, the retreating North Korean forces who had gained control of the area shot more than forty American POWs on Hill 303.
